Durox Supabloc Aircrete Blocks - high thermal insulation
Durox Supabloc are the most versatile aircrete blocks available. These lightwieght aerated concrete blocks provide the best combination of compressive strength and low thermal conductivity. They also achieve the acoustic performance standards required by Building Regulations for internal walls in dwellings.
Durox Supabloc working dimensions
Face dimensions are 620mm long x 215mm high.
50mm Supabloc is available at a face size of 310mm long x 215mm high.
